SPECIFICATION formingpart of Letters Patent No. 501,347, dated July 11,1893.

Application filed September 22, 1892. Serial No. 446.617. (No model.)

T all whmn it may concern.-

-Be it known that I, ALFRED INSINGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inDish-Washin g Machines; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates, generally, to dish washing machines, andparticularly to that class of machines which are used in hotels,restaurants and the like places where dishes are to be washed hurriedlyand in large quantities, and it has for its object to provide a machineby which the dishes may be expeditiously and thoroughly washed andrinsed in large quantities Without liability of chipping or breaking thesame during the operation, and it consists in the parts and combinationsof parts hereinafter fully described and pointed out in the claims.

In the accompanying drawings forming a part of this specification Figure1 is a side elevation of my improved machine as set up for operation;Fig. 2 a plan view of the machine, proper, with the top removed from thewashing tank; Fig. 3 a longitudinal horizontal sectional view on theline zra;, Fig. 1; Fig. 4 a longitudinal vertical sectional view of thewashing tank on the line yy, Fig. 2; Fig. 5 a transverse verticalsectional view of the same on the line 2-2, Fig. 2; Fig. 6 a detailperspective view of thebasket platform of the washing tank and the meansfor operating the same; Fig. 7 a detailplan view of the valve for thedrain pipe; and Fig. 8 a longitudinal sectional view of the same.

Similar letters refer to similar parts th roughout the several views.

A represents the washing tank and B the rinsing tank of my improvedmachine, said tanks being arranged adjacent each other and connected bya removable board a, Fig. 1, which serves to protect the pipes andgearing arranged or located between the adjacent ends of the tanks fromthe drippings from the basket A containing the dishes during thetransfer of the same from one tank to the other.

C is an inclined drip-board secured in any desired manner to the end ofthe rinsing tank on which the basket A rests or is supported after thedishes have been rinsed to permit of the water draining therefrom backinto the rinsing tank, before removing the dishes therefrom. The basketA is formed, preferably, of galvanized iron wire arranged so as to leaveinterstices of such size as to permit of the water entering freely onall sides and the bottom, but any other suitable foraminous orreticulated material may beused to form the basket if desired. Withinthe basket a series of transverse upright partitions 1) is secured,between which the soiled dishes are set on edge in the basket, therebypreventing said dishes, during the agitation of the basket whilecleansing the same, from being displaced or violently thrown or shakenabout in the basket and against one another, thus reducing the liabilityof breaking and chipping the same during the operation of the machine.

The baskets A are each provided with a bail c by which they may beraised and lowered in the tanks and transferred from one to the other bymeans of a chain 01 having a hook e at one end and a handle f at theother, said chain passing over a grooved pulley g suspended by a hangerh from a hook i pivotally secured to a grooved wheel j supported on asemi-circular rail 70 and fitted to a semicircular guide rail Z arrangedabove said rail is. The rail Z issecured to the ceiling of the room sothat one-half thereof extends over the tanks of the machine or to aframe specially built therefor, and rail is is supported therefrom byhangers m. From the above description it will be understood that thebaskets are first carried to the washing tank A, from the left hand sideFig. 1, and deposited therein and, when cleansed, are lifted thereout bythe chains 01 and moved over to the rinsing tank B and there immersedand from this tank they are raised and moved onto the drip-board O andthe surplus water drained therefrom back into the rinsing tank and whensufficiently drained the baskets are again moved on the rail it to atable and the dishes. removed therefrom. It will be observed, therefore,that a large quantity of dishes may be cleansed in a short space oftime, as while one basket of dishes is being washed in the tank Aanother basket may be immersed in the rinsing tank and a third basket beresting on the drip-board, thus rendering the operation of cleansing thedishes, practically, continuous.

The tanks A and B are formed of an inner lining and bottom of sheetmetal a and an outside covering of wood 0, and a grid or grated frame 19is arranged therein near each end of the respective tanks which extendsfrom one side wall thereof to a vertical partition (1 arranged near theopposite side wall, said partition q, as best shown in Fig. 2, being letinto the end walls of the tanks, and, as shown in Fig. 4, beingsupported by an extension 0" which rests on the bottom of the tanks. Theends of the grid 19 are let into or fitted in grooves formed in thepartition q and the side walls of the frame, see Fig. 3, and rest attheir lower ends on an offset, as at s, Fig. 4, formed on the edge ofthe curved partition or housing D and are held in place by turn buttonst, Fig. 5, pivotally secured to a partition E extending across the upperpart of the tanks from one side wall to the'partition q. The housingDextends partly across the tanks and from the partition E to the endwalls of the tanks, and form the chambers within which the propellers,to be hereinafter described, operate.

As shown in Fig. 4, the curved partition rests at one side on the bottomof the tank, the other side of which terminates some distance above thebottom and against the partition q, as at 'v, and said housing iscutaway, as at *0, on both sides to permit of the ready access of thewater to the propellers. It will thus be seen that the water on whichthe propellers operate is confined within a limited space so that thepropellers may force or throw the same in but one directionoutward andthrough the grid frame p, and that -the water returning to thepropellers to be again operated upon has ample space through which tofind its way to the chambers at each end of the tank.

At each side of the washing tank a bracket Fis mounted through a slot inits vertical arm on a headed pin G, said bracket being formed with twohorizontal armsuprojecting at right angles on which the ends of thegrated platform H rest when in operative position. A lever I is pivotedat one end to the side walls of the tank A and at its center to a pin Jprojecting from and secured to the front face of the bracket, as bestshown in Fig. 6. At each side of their central pivotal points the leversI are formed with curved projections K which extend vertically from theupper and lower edges of said levers and, hearing against the side wallsof the tank, act as guides to retain the levers in theirproperpositionsduring their movement. At their free ends the levers I are somewhatenlarged and rest on the enlarged free ends of levers L which arepivoted, at M, to one end wall of the tank the other ends of said leversL passing each other and extending under and in position to be struck byan eccentric N mounted on a shaft 0, whereby said levers may be rockedon their pivots and the levers I swung thereby vertically, thus raisingand lowering the brackets and imparting a rapid vertical movement to theplatform H supported by said brackets.

On the platform H of the washing tank the basket A containing the soileddishes is sup ported during the operation of the machine and is carriedup and down with said platform, the pins G on which the brackets F moveinsuring the direct vertical movement of the platform on a horizontalplane orlevel, so that there is no liability of the platform or thebasket wabbling or turning to either side. This movement of the basketup and down in the water contained in thetank creates cross currentshaving a vertical tendency which, in connection with the horizontalcurrents created by the propellers, materially facilitates the cleansingof the dishes.

The propellers P are mounted on shafts O, Q and R, the two latter beingstub shafts having their bearings, at the ends of the tanks A and B nearone side, in water tight journal boxes consisting of a cylindrical box ahaving an enlarged end formed with screw threads to receive a cap I)through which the shafts pass. The interior diameter of said boxes beinggreater than the diameter of the shafts permit of any suitable packingbeing arranged therein about the shafts, as shown in Fig. 3. A flange cis cast with or secured to the boxes through which screws or bolts maybe passed to secure the boxes to the metal walls of the tanks. The shaft0 is arranged between the adjacent ends of the tanks and its endsproject into said tanks, the eccentric N being suitably secured to thatend of the shaft which extends into the washing tank.

The rinsing tank B is provided with housings and partitions and platformin all respects similar to that of tank A, but as its platformis notagitated during the operation of the machine it rests on or is securedto pins (1' projecting from the bottom of said tank.

To one side of the tanks a horizontal shaft S is journaled in suitablebearings, said shaft projecting at each end beyond the ends of the tanksand having the cranks e and f formed on or secured thereto at one end.To the crank e the end of a piston rod g of an engine T is attached andto crank f the stem h of the valve rod of said engine is connected, theengine, for convenience sake, being mounted on the end of the rinsingtank and receiving its steam thronghapipe z" from any suitable steamgenerating apparatus. A pulleyj' ismounted on shaft S and is connectedby a crossed belt to a similar pulley Z mounted on the end of shaft Qand imparts motion thereto in a direction opposite to that of the mainshaft S and similar pulleys, m, n, are mounted, respectively, on themain IIO shaft and the shaft R of the. tank A which are also connectedby a crossed belt 0' so that said shaft R is revolved in a directionopposite to that of shaft S. At about the center of the shaft S asprocket wheel p is mounted which is connected with a sprocket wheel qmounted on the shaft 0 by a sprocket chain 4* thereby imparting motionto said shaft 0 in the same direction as shaft S. A balance wheel T. ismounted centrally of the shaft. The result of this arrangement of thedriving or operating mechanism is that the propellers, in .each tank,are rotated in opposite'direc-j tions and, as saidpropellers arearranged diagonally opposite each other in their respective tanks,currents of water are created which are forced across the tankdiagonally, that is from the ends across the centers of .the tankstoward the side walls as indicated bythe arrows, Fig. 3, said currents,owing to the position of the propellers relative to each other, notconflicting or interfering with each other to any appreciable degree.It. will be observed that the currents being forced through the gridframe are scattered somewhat and that they enter the basket through theinterstices thereof with sufficient force and volume to disintegrate anddislodge any adhering particles of matter from the dishes.

The tanks are supplied withwater through the pipes U which are connectedto the main cold water pipes U and hot water pipes U by a T-coupling Uconnecting said hot and cold water pipes, both of which are providedwith valves to regulate the supply of water and lead to any desiredsource of supply. In order to maintain the water in the tanks at thedegree of heat necessary to the proper cleansing of the dishes, I runapipe A from the exhaust pipe B of the engine under the rinsing tank B toa pipe 0 from which pipes D and E lead into the tanks A and B,'neartheir bottoms, and extend around three sides of the same and, emergingtherefrom atthe sides opposite which they entered the same, areconnected to an escape pipe F. The pipes O and F are both provided withsuitable valves so that the steam may be regulated and directed intoeither or both tanks and the escape of steam regulated as desired.

In the bottoms of both tanks I form elongated openings G through whichthe Water may be discharged. To'the bottoms of each of the tanks Isecure a valve chest H over said dis charge opening (see Figs. 7 and 8),in any desired manner to which is connected one end of the dischargepipes I and 1 for the rinsing tank and washing tank respectively andwithin the chest I seat a valve J having an arm K formed on the end ofan upright stud L which extends downwardly through an openingin thebottom of the chest, which is rendered water tight by a plug h and has alever N connected to its lower end, said lever extending outwardly andinto a position to be moved by the foot of the attendant to open orclose the discharge openings. The discharge P provided with a hingedcover R is arranged at one side ,of each tank and is connected with thedischarge pipes I and I by pipes S as best shown in Figs. at and 5; Acover T is arranged over the chambers in. which the propellers work toprevent the water from being thrown out of saidochambers, and a coverhaving an opening formed centrally therein through which the baskets arepassed is provided for each tank.

From the above description it willbe understood that a circulation ofwater is created Within the tanks, passing around the sides thereof andentering the chamberscontaining the propellers atthe ends thereofthrough open: ings v and that the curved or twisted blades of thepropellers lift the water and forcibly eject the same in continuousstreams through the grid frame. Also it will be noticed that I utilizethe exhaust steam from the engine to maintain the heat of the water inthe tanks to the desired or necessary degree for thoroughly cleansingthe dishes. I

Having thus described my invention, what I claim asnew, and desire tosecure by Letters Patent, is v 1.
